Control system of electric excavator and electric excavator
The invention provides an electric excavator control system and an electric excavator, and relates to the technical field of excavator control. The electric excavator control system comprises a powersubsystem, an AC power supply subsystem, a battery pack power supply subsystem and a control subsystem; the AC power supply subsystem is connected with the power subsystem through a first relay; the battery pack power supply subsystem is connected with the power subsystem through a second relay; when the AC power supply subsystem supplies power normally, the first relay is switched on, and the second relay is switched off. The control subsystem is used for controlling the second relay to be closed when the AC power supply subsystem has a power supply fault. According to the control system of the electric excavator and the electric excavator, due to the fact that the battery pack power supply subsystem is arranged, when an external power source breaks down, power can be supplied through thebattery pack power supply subsystem, and the safety of equipment and personnel is guaranteed.
本发明提供了一种电动挖掘机的控制系统及电动挖掘机，涉及挖掘机控制的技术领域，包括：动力子系统、交流供电子系统、电池组供电子系统和控制子系统；所述交流供电子系统，通过第一继电器与所述动力子系统连接；所述电池组供电子系统，通过第二继电器与所述动力子系统连接；所述交流供电子系统供电正常时，所述第一继电器闭合，所述第二继电器断开；所述控制子系统，用于在所述交流供电子系统供电故障时，控制所述第二继电器闭合。本发明提供了一种电动挖掘机的控制系统及电动挖掘机，由于设置有电池组供电子系统，在外接电源出现故障时，可以通过电池组供电子系统供电，从而保障设备及人员安全。
